With the continuous development of industry, it has brought a lot of convenience to human production and life, but environmental pollution has also become a thorny problem that people have to face, especially sulfur dioxide pollution has become one of the main pollutants in the air environment. Therefore, the requirements for desulfurization treatment in industrial production are becoming more and more stringent, and the use of high-efficiency desulfurization catalysts has played an important role in desulfurization operations.
1. Application range of high-efficiency desulfurization catalysts
1.Oil and gas industry
In recent years, the development of China's oil and gas and other chemical industries has accelerated, and liquefied oil and gas must be desulfurized first in the process of chemical production and application, so the development and improvement of liquefied oil and gas desulfurization technology and the application of high-efficiency desulfurization catalysts are becoming the key to the production of China's chemical industry.
2.Power industry
At present, most power plants in China still use traditional thermal power generation, and thermal power generation generally uses coal, so it is necessary to use high-efficiency desulfurization catalysts in the power industry to improve the sulfur generated in the power generation process.
3.Coal chemical industry
The coal chemical industry uses coal as raw material, and converts coal into gas, liquid and solid products or semi-products through chemical processing, and then further processes it into chemical and energy products, mainly including coal gasification, liquefaction, dry distillation, tar processing and calcium carbide acetylene chemical industry. Sulfur is inevitably produced in the production process of the coal chemical industry, so high-efficiency desulfurization catalysts are indispensable in the coal chemical industry.
2. Precautions for the use of high-efficiency desulfurization catalysts
1.Do not stop adding the original desulfurizer when you use it for the first time, so that it will not affect the normal production, and wait until 2-3 days later, you can stop adding the original desulfurizer, which can be better connected with the original desulfurizer.
2.It is not possible to use ammonia carbide containing additives in the carbonization chemical section, when ammonia is used as an absorbent; It can not be mixed with copper liquid, and when the ammonia is washed with copper, it is easy to affect the foam flotation.
3.When the H2S content of coke oven gas exceeds 5g m3, soda ash should be used as the alkali source; Shift gas desulfurization should use soda ash as the absorbent.
4.Strong hygroscopicity composition of a very stable desulfurization catalyst, suitable for storage in a cool and dry place, if the opening is not properly kept, and the debris mixed will affect the use.
